选定因素下湿地基质释放氮的正交试验研究

, 2008
通过正交试验考察了成熟湿地基质在选定的影响因素及水平下的氮释放量。结果表明,25℃下氨氮的平均释放量是15℃下的2.9倍,亚硝态氮及硝态氮的释放量在两温度下无显著差异;35℃下氨氮的平均释放量是15℃下的5.6倍,亚硝态氮和硝态氮的释放量较15℃时有明显增加。由于湿地基质中COD的释放,在试验设定的进水COD浓度水平（≤40 mg/L）下,COD含量难以对氮的释放产生显著影响。湿地基质对pH有较强的缓冲能力 ...

Comparison tests on runoff and sediment yield process from earth road andplant-covered road in loess hilly region

, 2009
通过室内人工降雨+放水冲刷相结合的方法,对5个坡度(3~18°),5种雨强(1~3mm.min-1),5组放水流量(1.4~9.0kg.m-2.s-1)下的黄棉土土质路面和早熟禾植物路面进行了共60余场次试验,对比分析了植物路相对于土质路侵蚀过程差异及产水、减沙效果。结果表明:在放水冲刷条件下,植物路侵蚀率随放水历时降低,其过程可用对数函数描述;土质路面侵蚀率变化复杂。两类道路的放水流量与侵蚀强度均呈现幂函数变化,且植物道路表现出明显的防蚀作用。雨强增加引起径流量、侵蚀强度增加 ...
